some people say alcohol, some people say some gases in the right environments and pressures (gas giants), maybe even very powerful magnetic feilds.

i'd like to think its as simple as there being enough potential for energy conversion within a system, as well as chemicals for storing information like dna which requires at least in our evolution acids of all sorts, either just chemically or through such systems as catalysing solar radiation with gases and liquids, also a good argument for life in the higher atmospheres of gas giants.

a funny thing is all the planets we find that are gas giants right up close to their stars, they would be good breading ground for life if the temperatures weren't too hot, or the planets spin to high or slow.

but the question is can intelligent tool using, writing, social animal develop in floating environments like clouds or oceans. it's likely that we developed as we did as a direct result to having adapted to several environments, land, sea, air, low oxygen concentrations, sea level, we've adapted to them all and are more powerful because of those adaptations. without different environments their is less likelyhood that a creature will continue to evolve past a point where they can survive comfortably.
